ORP is a measurement of Oxidation Reduction Potential(mV) most commonly used to measure the effectiveness of water disinfection systems using sanitizers such as Chlorine, Bromine, Ozone, Peroxyacetic Acid, Hydrogen Peroxide etc. It is also commonly used in waste water treatment for oxidation of cyanide waste, chrome reduction etc. ORP standards have been long established for water sanitation, and are recommended over ppm measurements with traditional test kits. All ORP testers must purchase with calibration solution for tester calibration |
